Such a fun setting I played this module with two different groups! The second time I modified the story, but reused characters and places. There's just so much creative material to work with in this.
It took three hours the first time -- the group skipped the Rat Boss encounter entirely, since it sounded "too obvious" to them. They enjoyed checking out all the sideshow attractions, even after finding out where Balink was.
I left out the half-ogre encounter for the second group. They did go to the rat boss but then they went straight for the mermaid and skipped the other sideshows. Their session took two hours.
My players had fun discussing what happened between the two groups. I look forward to bringing back a certain cat or two for future encounters.
